Which conversion method is better?

Convert.ToInt32 or Int.Parse which is better and why? Is there any specific condition where i can use these two?.

If you don't expect null to ever be passed as the argument, use int.Parse, since then you'll be alerted via an exception when something does go wrong.

From Reflector:

public static int ToInt32(string value)
{
    if (value == null)
    {
        return 0;
    }
    return int.Parse(value, CultureInfo.CurrentCulture);
}

So calling int.Parse() would be a little quicker.

Convert.ToInt32 internally calls Int.Parse with a null check. So the Null check is extra and does not throw in case of a Null parameter.

You can refer to this question here: Any performance difference between int.Parse() and Convert.Toint()?

Presumably you're asking about the Convert.ToInt32 which takes a string. In that case, it simply calls int.Parse internally, so there's no real difference except that Convert gracefully handles null by returning 0.

One of them calls the other (though I can't remember which is which ATM), so there's no practical difference between them.
